  2. Inclinometer - Wikipedia

    en.wikipedia.org/wiki/Inclinometer

    The Abney level is a handheld surveying instrument developed in the 1870s that includes a sighting tube and inclinometer, arranged so that the surveyor may align the sighting tube (and its crosshair) with the reflection of the bubble in the spirit level of the inclinometer when the line of sight is at the angle set on the inclinometer.

  3. Tiltmeter - Wikipedia

    en.wikipedia.org/wiki/Tiltmeter

    A newer technology using microelectromechanical systems (MEMS) sensors enables tilt angle measuring tasks to be performed conveniently in both single and dual axis mode. Ultra-high precision 2-axis MEMS driven digital inclinometer/ tiltmeter instruments are available for speedy angle measurement applications and surface profiling requiring very ...

    To do this, distinct ends of an organism are chosen, and the axis is named according to those directions. An organism that is symmetrical on both sides has three main axes that intersect at right angles. [3] An organism that is round or not symmetrical may have different axes. [3] Example axes are: The anteroposterior axis [8] The cephalocaudal ...

    en.wikipedia.org/wiki/Random_positioning_machine

    The RPM is a more sophisticated development of the single-axis clinostat. RPMs usually consist of two independently rotating frames. RPMs usually consist of two independently rotating frames. One frame is positioned inside the other giving a very complex net change of orientation to a biological sample mounted in the middle.

    There’s no single explanation for why addiction treatment is mired in a kind of scientific dark age, why addicts are denied the help that modern medicine can offer. Family doctors tend to see addicts as a nuisance or a liability and don’t want them crowding their waiting rooms. In American culture, self-help runs deep.

  9. Biological screw joint - Wikipedia

    en.wikipedia.org/wiki/Biological_screw_joint

    The biological screw joint is a naturally occurring form of the screw joint, a mechanical device that combines rotational movement with single-axis translation.Alexander Riedel of the State Museum of Natural History Karlsruhe and Thomas van de Kamp of the Karlsruhe Institute of Technology [1] discovered it in specimens of Trigonopterus oblongus, a weevil found in Papua.
